What is the grade of the hadiths regarding the prayer of tasbih?

The first message in this episode came from a Yemeni sister who said in her message: I am an illiterate woman who does not know how to read, and I do not memorize from the Noble Qur'an except the short surahs. When the blessed month of Ramadan enters, I have been praying the prayer of tasbih for the entire month for fifteen years. I prayed it, and I heard a fatwa on your program stating that this prayer is not prescribed and that it is a religious innovation, so I refrained from this prayer for two years. However, I heard from one of the religious men that whoever prays it once a week, once a month, once a year, or once in his lifetime has a great reward. When the month of Ramadan came this year, I returned to praying it. I ask you to clarify this. May Allah reward you.
Answer: In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, and may Allah send blessings and peace upon the Messenger of Allah, upon his family and his Companions, and upon those who follow his guidance.
As for what follows:
The prayer of tasbih has some hadiths reported regarding it, but according to the scholars of verification, they are weak hadiths that are not authentic. Therefore, it should not be performed. As for what has passed, you have the reward for your ijtihad, if Allah wills. As for the future, we advise you not to perform it, because the hadiths of the prayer of tasbih are not authentic; rather, they are anomalous and contradict the authentic, established hadiths from the Messenger of Allah (peace and blessings be upon him) regarding the description of the prayer. Yes.
The presenter: May Allah reward you.
